Good things come in threes.

The Oceanic VEO 3.0 continues Oceanic's tradition of designing rugged, feature-rich personal dive computers that are intuitively easy to use and reasonably priced. Featuring Oceanic’s exclusive Dual Algorithm, 2-Nitrox Mix Compatibility, Audible Alarms, 3-Button Interface with settings "Step Back", and so much more.  All in a strong, lightweight "hockey-puck" module for your wrist or console. Now available with metric system.


  • Powered by Oceanic's Exclusive Dual Algorithm™ - Your choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis)
  • 3 Operating Modes: NORM (Air and Nitrox), GAUGE (with run timer) and FREE (tracks calculations to allow switching between NORM and Free)
  • 3 Operating Buttons with "Step Back" interface – allows forward and backward navigation through menus and settings
  • Switch between up to 2 Nitrox mixes to 100% O2 with no restriction (Gas 1 may be up to 100%, and may be less or greater than Gas 2)
  • Stop times < 3 minutes - displays minutes & seconds
  • Deep Stop with Countdown Timer – Maybe turned on or off.  2 minute countdown at half your max depth, for dives greater than 80 ft / 25m
  • Single button access to "Last Dive" display (max depth & bottom time)
  • Data Retention - maintains calculations indefinitely when the battery is changed
  • Audible Alarm with flashing LED light
  • SmartGlo Backlighting senses ambient light, enabling the backlight only in low light conditions, conserving battery life
  • 24 dive on-unit log book
  • History Mode includes total number of dives, max depth, total dive hours, and lowest temp
  • Optional PC Interface with OceanLog Download and Settings Upload
  • Firmware Auto-Update: download and install the latest firmware – these may be operational improvements or even new features
Dual Algorithm Technology

Dual Algorithm Technology

Choose the one dive computer that’s liberal, conservative or middle-of-the-road.

Dual Algorithm™ technology lets you choose the decompression algorithm that best suits your diving needs without compromising safety.


repetitive deep and decrompression dive profile


Choose Pelagic DSAT for:

Liberal Recreational Diving

The Pelagic DSAT Algorithm safely maximizes dive time for repetitive, multi-level recreational diving. This algorithm relies on the human Doppler studies used to develop PADI’s Recreational Dive Planner (RDP), and has been the basis of our Dive Computers and other manufacturer's computer algorithms for many years. 

To add additional conservatism, you can also adjust the:

  • Tissue-Loading Bar Graph Alarm
  • Conservative Factor Setting


Choose Pelagic Z+ for:

Conservative Recreational Diving

When applied to standard recreational diving, the Pelagic Z+ Algorithm basis increases the conservative factor of the OC1 by 15-20%.

Liberal Repetitive Deep and Decompression Diving

The Pelagic Z+ uses the Buhlmann ZHL-16C database, which was conducted to meet the more rigorous demands of repetitive, cold-water decompression diving at altitude. The Pelagic Z+ mode maximizes dive times at depth without penalties.

Dive in sync with any buddy, anywhere.

Because the Dual Algorithm allows you to adjust the algorithm basis and its conservatism, you can adjust to closely match just about any other dive computer on the market, allowing you and any buddy to always dive in sync. Diving the same profile increases safety for both divers, and eliminates the need for one person to conduct a much longer or deeper stop when buddying with someone wearing a more liberal dive computer. On repetitive dives, there is no more waiting for the more conservative dive computer to clear. Both buddies will be ready to enter the water at the same time and can continue to dive the same profiles. You can’t control which dive computer your buddy wears, but you can control your ability to dive the same profile.

A note about deep stops:

Both algorithms allow (user ON/OFF option) credit for deep stops for No-Decompression dives in keeping with the data of Morroni et al (2004) and Bennett et al (2007).  No penalty is given if the diver skips the deep stop, but it is strongly recommended that a shallow safety stop be made with or without the deep stop in keeping with the experiments of Pilmanis (1975). 

It is important to note that neither algorithm provides deep stops for decompression dives since there is ample experimental data [Blatteau et al (2005), Gerth et al (2007), and Gutvik et al (2007)] that indicate that this practice often produces an increase in the risk of DCS.

Almost great computer
Review by Dalton (Posted on 11/30/14)
I have this Veo 3.0 for 3 years now (and 120 dives) and i almost could say its great!...the only think i really don't like is the not very user friendly software. the structure of this menus is not my favorite at all.; but besides that i can say its great!. I will keep it :)
Great Computer
Review by Stephen (Posted on 11/5/14)
This computer has a great primary screen layout with all of the data you need at a glance in large easy to read graphics. The functions are very intuitive and are much easier to navigate than the competition. I have dived this computer in the tropics as well as cold water wreck diving and this computer has performed admirably.
great computer
Review by mikeyjbarry (Posted on 11/2/13)
I have used for about three years with no issues. I wish they had software for mac computers as well.
As expected GREAT!
Review by Ohio traveller (Posted on 8/30/13)
Have 170 dives with this computer, always dependable. Changed batteries multiple times always before a live-a-board, no issues but do use caution to close compartment. One has older software that needs to be upgraded to improve log book feature for O2 readings. Logbook works great with Windows for all 170 dives. Our family has 4 Oceanic computers and when compared on the same dive the data is equivalent.
Almost Five Stars
Review by Jeep (Posted on 3/7/13)
I like everything about my Veo 3 save for the fact that Oceanic has yet to update its software so that I can sync my watch with my Mac.
Great but...
Review by Faap (Posted on 1/29/13)
I wish they have software for the Mac computers in order to sync and keep the log.
Other point is switching gases is not user friendly, need to change the way to do this more easily
Great! but...
Review by jairrami (Posted on 4/14/12)
So far I'm really happy with my Veo 3.0. But I wish they have software for the Mac computers in order to sync and keep the log.

** Oceanic Personal Dive Computers have user selectable Sampling Rates that determine when data is sampled and stored for subsequent download to associated PC interface programs. More frequent sampling provides more data per dive yet results in storage of fewer dives for download. Use with Air or Nitrox, with or without air integration, dive profiles, Free Diving activities, and other variables may also affect the number of dives that can be stored.
